“…Some ecological, biochemical, molecular and geneticapproaches should also be integrated for developing of novel technologies (Gorai et al 2020). Based on the recent studies, many researchers confirmed the role of Trichoderma in the bioremediation of many organic contaminants such asTNT by Trichoderma viride (Alothman et al 2020), chromium by by Trichoderma viride (Zapana-Huarache et al 2020), and copper or chromium by Trichoderma lixii CR700 Dwivedi 2019, 2021), diesel byTrichoderma harzianum strain T22 (Elshafie et al 2020), and polycyclic aromatic hydrocarbons by T. longibrachiatum (Li et al 2021).…”

T HE world's burgeoning population faces a great challenge concerning food security, which could be achieved through different sustainable agricultural practices. Trichoderma, as a ubiquitous fungus, is one of the most promising microorganisms that might offer several avenues for sustainable agriculture. Trichoderma spp. may guarantee a better solution for conventional problems in agriculture through several approaches including the protection of cultivated plants from undesirable abiotic and biotic conditions under changing environments and promoting their growth in poor or limited soil nutrients. The promising role of Trichoderma for vegetable production as a biocontrol and biofertilizers has been confirmed but its role as a plant pathogen still needs more studies. Trichoderma could inhibit or suppress the growth of soil phytopathogens, promoting plant growth and soil health, through activation of many mechanisms including synthesis of antibiotics, mycoparasitism and competition for nutrients and space against plant deleterious microorganisms. The sustainable approaches of Trichoderma including biofortification, bio-remediation and phyto-remediationas well as exploring future research opportunities will be also addressed in this work.

“…Considering the influence of pollution on the bacterial composition, the changes in the relative abundance of Firmicutes and Proteobacteria were almost the largest. These two phyla have strong adaptability and are the dominant microbes in many soils under heavy metal stress ( Drzewiecka, 2016 ) and play an important role in the degradation of PAHs ( Sun et al, 2010 ; Li et al, 2021b ). Furthermore, principal coordinate analyses (PCoA) on Bray–Curtis distances were performed to investigate the variation in microbial communities in different rhizocompartments under separate treatments ( Figure 3 ).…”

Combined organic and inorganic pollutants can greatly impact crops and microbes, but the interaction between coexisted pollutants and their effects on root-associated microbes under flooding conditions remains poorly understood. In this study, greenhouse experiments were conducted to investigate the individual and combined effects of phenanthrene (PHE) and copper (Cu) on rice uptake and root-associated microbial coping strategies. The results showed that more than 90% of phenanthrene was degraded, while the existence of Cu significantly reduced the dissipation of PHE in the rhizosphere, and the coexistence of phenanthrene and copper promoted their respective accumulation in plant roots. Copper played a dominant role in the interaction between these two chemicals. Microbes that can tolerate heavy metals and degrade PAHs, e.g., Herbaspirillum, Sphingobacteriales, and Saccharimonadales, were enriched in the contaminated soils. Additionally, microbes associated with redox processes reacted differently under polluted treatments. Fe reducers increased in Cu-treated soils, while sulfate reducers and methanogens were considerably inhibited under polluted treatments. In total, our results uncover the combined effect of heavy metals and polycyclic aromatic hydrocarbons on the assemblage of root-associated microbial communities in anaerobic environments and provide useful information for the selection of effective root-associated microbiomes to improve the resistance of common crops in contaminated sites.

“…DNA‐SIP with C 13 labeled hydrocarbons identified several aliphatic ( Alcanivorax , Marinobacter ) and PAH ( Alteromonas , Cycloclasticus , Colwellia ) degrading bacteria [140]. The technique was further applied to compare the bacterial community shift in treated soil samples [141]. The taxonomic composition of operational taxonomic units from myco‐remediated soil sample showed the dominance of proteobacteria comprising gamma‐proteobacteria (31.2%), beta‐proteobacteria (16.1%), alpha‐proteobacteria (14%), and delta‐proteobacteria (5.6%) compared with untreated or lignocellulosic material treated soil sample [141].…”

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous high global concern environmental pollutants and tend to bioaccumulate due to hydrophobic properties. These xenobiotics, having variable concentrations along different matrices, gradually undergo various physical, chemical, and biological transformation processes. Myco‐remediation aids accelerated degradation by effectively transforming complex ring structures to oxidized/hydroxylated intermediates, which can further funnel to bacterial degradation pathways. Exploitation of such complementing fungal−bacterial enzymatic activity can overcome certain limitations of incomplete bioremediation process. Furthermore, high‐throughput molecular methods can be employed to unveil community structure, taxon abundance, coexisting community interactions, and metabolic pathways under stressed conditions. The present review critically discusses the role of different fungal phyla in PAHs biotransformation and application of fungal−bacterial cocultures for enhanced mineralization. Moreover, recent advances in bioassays for PAH residue detection, monitoring, developing xenobiotics stress‐tolerant strains, and application of fungal catabolic enzymes are highlighted. Application of next‐generation sequencing methods to reveal complex ecological networks based on microbial community interactions and data analysis bias in performing such studies is further discussed in detail. Conclusively, the review underscores the application of mixed‐culture approach by critically highlighting in situ fungal−bacterial community nexus and its role in complete mineralization of PAHs for the management of contaminated sites.
